追憶 -ついおく-

A year after your graduation, you've become a security guard, and your first post happens to be at your old school, where you used to be the president of the student council.

But everything there seems off: the school is set to close, and everyone you knew seems depressed, or acts strange. Nothing like the flourishing school it was a year ago. And nobody will answer your questions about how this happened.

To your surprise, you get a chance of being the student council president once more and right the wrongs that have happened.
